Buggy code:

Fix:
assertTrue ( ( ( ( ( i + "-th<seq2seq4repair_space>SQL<seq2seq4repair_space>for<seq2seq4repair_space>JPQL:<seq2seq4repair_space>" ) + ( jSQL . get ( i ) ) ) + "<seq2seq4repair_space>are<seq2seq4repair_space>different<seq2seq4repair_space>than<seq2seq4repair_space>Expected<seq2seq4repair_space>SQL<seq2seq4repair_space>" ) + expectedSQL ) , expectedSQL . equalsIgnoreCase ( jSQL . get ( i ) ) ) ;
